'Game of Thrones' Season 4 First Trailer: Which Side You're On

Jon Snow is preparing for the battle against the Wildlings, Tyrion is arrested and Cersei makes a threat as the tension is rising in Westeros.

HBO fulfilled its promise by debuting the first full trailer for "Game of Thrones" season 4 on Sunday, December 12. The video opens with King Joffrey bragging about him winning a war, but Jaime Lannister, back in his good shape, telling him, "The war is not won."

Joffrey and Margaery's wedding is approaching, but the Lannisters are still at each other's throats, with Cersei making a serious threat. Tyrion is arrested and tells someone unseen, "If you want justice, you've come to the wrong place."

Elsewhere, Jon Snow is ready to lead a battle against Wildlings who are marching down from the North. Daenerys continues gaining her power, giving an ultimatum to her new people, "They have a choice: they can live in my new world or they can die in their old won."

A glimpse of Yara Greyjoy sailing with her soldiers, Bran touching a tree and Arya looking cautious is also shared. Petyr "Littlefinger" Baelish asks someone to say which side he's on, while Melisandre says, "There is only one hell - the one we live in now."

The new season of "Game of Thrones" is set to premiere Sunday, April 6, at 9/8c. It will introduce new faces such as Red Viper a.k.a. Prince Oberyn (Pedro Pascal), Tycho Nestoris (Mark Gatiss), Styr of the Thenn (Yuri Kolokolnikov), and Hizdahr zo Loraq (Joel Fry).
